Pros: Bought a few of these, they were all 100% functional under Windows, Linux and OSX.

Cons: Cable is short, but that be actually be handy.

Overall Review: I will continue to buy this product.

Called Sonnet for support. They ask to call Dell. Called Dell support, they said to call Sonnet support. Called Sonnet for a second time, they said their device is not compatible with this Dell laptop and asked us to return the device. They didn't explain why it was not compatible.
